"We are excited to continue to be here in Maryland, our home base for North America," Bowie said.
O'Malley called Knorr's new facility "phenomenal" and its $28 million investment in the state "colossal."
He said Knorr's new plant meets the state's "imperative of jobs, jobs, jobs."
"There is no progress without a job," O'Malley said. "The most important priority we have therefore is jobs and job creation."
Knorr expects to hire 40 to 50 more employees, including workers, engineers and program managers, within the next year to keep up with demand, according to Ken Towns, Knorr vice president for contracts.
"The transit market is growing, and we see continued growth in the next five years," Bowie said.
Knorr employees began moving into the new building on Arthur Peck Drive — which houses all office, warehouse and manufacturing operations — on April 6. All business operations are now up and running at the new site.
Towns said a lack of space on Baltimore Boulevard made the move to a new location necessary.
In addition to renting space from surrounding businesses, Towns said there was no space for employee parking.
Knorr broke ground for its new facility in January 2012.
An additional 160,000 square feet is available for expanding the building in the future.
McMullin said Knorr's expansion and planned expansions mean "the future is bright" with more jobs for Carroll residents.
Knorr's new facility is expected to received the Leadership in Energy and Environmental Design Gold certification, in part because of 3,036 solar panels that line the roof of the building. Those panels provide about 50 percent of all the energy the company needs.
The former Knorr building on Baltimore Boulevard did not remain vacant for long.
Newly formed Land Sea Air Manufacturing purchased the building earlier this month for $3.5 million. Employees began moving into the facility in early April and all operations should be up and running by June, according to Vice President Paul Virtz.
